Allocation loops
When allocating values, the calculated percentage is usually carried out on the highest hierarchy level.
You can use an allocation loop to adjust the percentage within the data area of the source, driver, or target, or all three data areas. When you enable the loop functionality for the source, the percentage within an element hierarchy is recalculated. It is then used as a source, driver, or target, depending on how the usage of the loop is defined.
You can enable looping when you select the reference dimension or data area of your source on the Allocation Parameterization page.
